ʻO ka manō salmon (Lamna ditropis) no ka papa o ka iʻa cartilaginous, ka ʻohana manō kauʻu.
Pālahalaha ka manō Salemona.
Hoʻolahalaha nui ʻia ka manō salemona ma nā kahakai a me nā pelagic āpau i nā latitude subarctic a me nā temperate o ka Moana Pākīpika ʻĀkau, aia ma waena o 10 ° N. sh. a 70 ° latitu ʻākau. Aia ka pae i ke kai ʻo Bering, ke kai o Okhotsk a me ke kai o Iapana, a hoʻonui ʻia hoʻi mai ke kahawai ʻo Alaska a i Kaleponi Hema. Loaʻa nā mano salmon i ka pae 35 ° N. - 65 ° N i ke kai komohana o ka Moana Pākīpika a mai 30 ° N. a i 65 ° N ma ka hikina.
Kahi noho manō o Salemona.
ʻO ka manō salemona he pelagic ka nui akā noho pū kekahi i nā wai kai. Noho mau lākou i ka papa wai o ka papa subarctic, akā e ʻau i ka wai hohonu o nā wahi hema o ka ʻāina ma kahi hohonu o 150 mau mika. Makemake kēia ʻano i nā mahana o ka wai ma waena o 2 ° C a me 24 ° C.
Nā hōʻailona kūwaho o kahi manō salemona.
ʻO ke kaumaha o ka manō salmon makua ma ka liʻiliʻi he 220 kg. ʻOi aku ka nui o nā manō ma ka hikina ʻākau o ka Pākīpika a ʻoi aku ka lōʻihi ma mua o ka manō ma nā ʻāina komohana. Hoʻololi ka lōʻihi o ke kino i ka nui mai 180 a 210 cm.
Noho ka mahana o ke kino o ka nui o nā iʻa me ka wela o ka wai e pili ana.
Hiki i nā mano salmon ke mālama i ke ana wela o ke kino ma mua o ke kaiapuni (a i ka 16 ° C). He kino kaumaha ko kēia ʻano manō, ʻano like me ka ihu pōkole a me ka lepe. ʻOi aku ka lōʻihi o Gill slits. Ākea a poepoe ka waha. Ma ka iwi ā luna, he 28 a 30 mau niho, ma ka iwi ā lalo - 26 27, he mau niho nui me nā niho ʻaoʻao (tubercles liʻiliʻi a i ʻole "mini-niho") ma nā ʻaoʻao ʻelua o kēlā me kēia niho. ʻO ka fin dorsal kahi o kahi fin dorsal lua nui a ʻoi aku ka liʻiliʻi. Liʻiliʻi ka fin anal. ʻO ke aniani caudal ke ʻano o ka crescent, kahi o ka dorsal a me nā ʻōpū o ka ʻōpū i aneane like i ka nui.
Nui nā peʻa pectoral i hui ʻia. ʻO kahi hiʻohiʻona kikoʻī ke kū ʻana o kahi keel ma ka peduncle caudal a me nā keels ʻelua pōkole kokoke i ka huelo. ʻO ka waihoʻoluʻu o ka hope a me nā ʻaoʻao ʻaoʻao he ʻeleʻele uliuli-hina i ʻeleʻele. Keʻokeʻo ka ʻōpū, a pinepine nā ʻano ʻeleʻele i ka poʻe mākua. ʻO ka ʻili ventral o ka ihuʻeleʻele hoʻi i ke kala.
Mano hoʻoulu mākala.
Mālama nā kāne kokoke i nā wahine, lālau iā lākou e nā pectoral fins ke hānau ʻia. A laila loli nā pālua, a ʻaʻohe pili hou o ka iʻa. E like me nā mano manele ʻē aʻe, nā kuleana ovary kūpono wale nō i nā manō salemona. ʻO ka hoʻoulu mea kūloko, a ulu ka ulu ʻana o nā embryo i loko o ke kino o ka wahine. ʻO kēia ʻano he ovoviviparous a pale ʻia nā embryos e hoʻomohala nei, hāʻawi kēia ʻano ulu i ke ola o nā keiki.
Aia i loko o ka moa he 4 a 5 mau mano ʻōpio i ka lōʻihi mai 60 a 65 cm.
Hānau ka manō salmon i ka wai ʻākau i 9 mau mahina i ka hāʻule, a hānau ka heluna o nā iʻa hema ma ka hopena o ka puna, ke kauwela mua. ʻO nā mano salemona wahine ma ka Pākīpika Komohana Komohana e hoʻohua i kēlā me kēia makahiki a hana ma kahi o 70 mau ʻōpio ʻōpio i ko lākou wā e ola nei. ʻOiai hānau kekahi kanaka ma ka ʻĀkau hikina o ka Moana Pākīpika i kēlā me kēia makahiki ʻelua. Hiki i nā kāne ke hoʻohua i ka lōʻihi o ke kino ma kahi o 140 cm a me nā makahiki o 5 mau makahiki, ʻoiai e hāʻawi nā wahine i nā keiki ma ka lōʻihi o ke kino o 170 a me 180 cm ke 8-10 mau makahiki. Loaʻa ka nui o nā mano salmon wahine i ka lōʻihi ma kahi o 215, a me nā kāne 190 cm. I ke ʻano, ola nā manō salemona no 20 a 30 mau makahiki. ʻAʻole mālama ʻia kēia ʻano iʻa i loko o nā aquarium nui, ʻaʻole ʻike ʻia pehea ka lōʻihi o ke ola ʻana o nā manō salmon i ka pio.
ʻO ka hana manō salmon.
ʻO ka manō salemona ka poʻe ʻaihue ʻaʻohe ona ʻāina paʻa a neʻe paha e ʻimi i kahi pio. Aia kekahi ʻokoʻa i ka lākiō o ka moekolohe ma kēia ʻano, i ʻike ʻia i loko o nā iʻa i loaʻa i nā ipu ʻĀkau a me ka Pākīpika.
Ua hoʻomalu ʻia nā heluna komohana e nā kāne, ʻoiai ua hoʻomalu ʻia nā heluna hikina e nā wahine.
Eia hou, aia he ʻokoʻa i ka nui o ke kino, ʻoi aku ka nui ma nā kānaka hema, ʻoiai ka liʻiliʻi o ka manō ʻākau. ʻIke ʻia nā manō salemona e huli hoʻokahi a ʻai paha i nā huhui o kekahi mau kānaka, mai 30 a 40 mau manō. He poʻe neʻe lākou i ke kau, neʻe mau ma hope o nā kula iʻa a lākou e hānai ai. ʻAʻohe ʻikepili e pili ana i nā pilina intraspecific i loko o nā manō salmon; ʻo kēia ʻano, e like me nā iʻa cartilaginous ʻē aʻe, kū i ke ʻano me ke kōkua o nā visual, olfactory, chemicals, mechanical and auditory receptors.
Mea ʻai pono a ka manō salemona.
Hana ʻia ka papaʻai o nā manō salemona mai nā ʻano iʻa like ʻole, mai ka salemona Pākīpika. Pau pū nā manō salmon i ka iʻa, Pacific herring, sardines, pollock, Pacific saury, mackerel, gobies a me nā iʻa ʻē aʻe.
ʻO ke kūlana kaiaolaola o ka manō salmon.
Aia nā manō salmon ma ka piko o ka pyramid kaolaola i loko o nā ʻōnaehana subarctic moana, e kōkua ana i ka hoʻoponopono ʻana i nā lehulehu o nā iʻa iʻa a me nā mea hānai kai. ʻO nā manō salmon liʻiliʻi mai 70 a 110 knm ka lōʻihi e pio ʻia e nā manō nui, e like me ka manō polū a me ka manō keʻokeʻo nui. A i nā manō salmon makua he hoʻokahi wale nō ʻenemi i ʻike ʻia e kēia mau mea ʻaihue - ke kāne. ʻAi a ulu nā manō salmon ʻōpio i loko o ka wai ma ke kūkulu ʻākau o ka palena subarctic, ua manaʻo ʻia kēia mau wahi he ʻano "nursery shark keiki". Ma laila lākou e pale ai i ka maka o nā manō nui, ʻaʻole ʻauʻau i loko o kēia mau wahi a alualu aku i ka ʻākau a hema paha. ʻAʻohe o ka manō ʻōpio i ka waihoʻoluʻu like ʻole o nā ʻaoʻao luna a me lalo o ke kino a me nā kiko ʻeleʻele ma ka ʻōpū.
He manaʻo no ke kanaka.
ʻO ka manō salemona kahi ʻano kalepa, mahalo nui ʻia kā lākou ʻiʻo a me nā hua me he huahana huahana lā. ʻIke pinepine ʻia kēia ʻano manō i nā ʻupena ma ke ʻano he iʻa i ka hopu ʻana i nā ʻano iʻa ʻē aʻe. I Iapana, hoʻohana ʻia nā ʻāpana kūloko o ka manō salmon no sashimi. Loaʻa kēia mau iʻa i ka lawaiʻa haʻuki a me nā hana hoʻokipa.
Hoʻoweliweli ʻia ka manō salmon e ka lawaiʻa kalepa. I ka manawa like, paʻa iʻa ka iʻa i ka seine a me ka ʻupena, waiho ka makau i nā ʻeha ma ke kino.
He mea weliweli paha ka manō salmon i nā kānaka, ʻoiai ʻaʻole i hoʻopaʻa ʻia nā ʻike i hoʻopaʻa ʻia e pili ana i kēia. ʻO nā hōʻike unsubstantiated o ka lawehala predatory o kēia ʻano i nā kānaka ma muli o ka kuhi hewa ʻana me kahi ʻano iʻoi aku ka hakakā e like me ka manō keʻokeʻo nui.
Ke kūlana mālama o ka manō salemona.
Ke helu ʻia nei ka manō salmon ma ke ʻano he holoholona "hemahema ʻikepili" no ke komo ʻana i ka IUCN Red List. ʻO nā helu haʻahaʻa o nā ʻōpio a me ka lohi o ka hana hou ʻana e maʻalahi ai kēia ʻano. Hoʻohui ʻia, ʻaʻole hoʻokau ʻia ka lawaiʻa manō salmon i loko o nā kai kūloko, kahi mea hoʻoweliweli e hōʻole i nā helu.
